Upgrade EastWest Gold XP Pro to Player version of Gold?

I've been loading my EastWest Gold XP Pro Symphonic Orchestra onto a new Windows 7 laptop. I'm finally moving off of my trusty XP desktop. Anyone have any recommendations? Should I take this opportunity (and spend $99) to upgrade to NI's newest "Play" platform? I've already spent a good chunk on the laptop, so if I can just run what I currently have in the new environment, I'd just as soon not upgrade. Anyone have experience with this? Let me know. Thanks!
